IMPORTANT SAFETY INFORMATION ABOUT MOVANTIK
- MOVANTIK® (naloxegol) is contraindicated in:
- Patients with known or suspected gastrointestinal (GI) obstruction and patients at risk of recurrent obstruction, due to the potential for GI perforation
- Patients receiving strong CYP3A4 inhibitors (eg, clarithromycin, ketoconazole) because these medications can significantly increase exposure to naloxegol which may precipitate opioid withdrawal symptoms
- Patients with a known serious or severe hypersensitivity reaction to MOVANTIK or any of its excipients
- Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, irritability, and yawning, occurred in patients treated with MOVANTIK. Patients receiving methadone as therapy for their pain condition were observed in the clinical trials to have a higher frequency of GI adverse reactions that may have been related to opioid withdrawal than patients receiving other opioids. Patients with disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal or reduced analgesia. These patients (eg, multiple sclerosis, recent brain injury, Alzheimer's disease, and uncontrolled epilepsy) were not enrolled in the clinical studies. Take into account the overall risk-benefit profile when using MOVANTIK in such patients. Monitor for symptoms of opioid withdrawal when using MOVANTIK in such patients
- Severe abdominal pain and/or diarrhea have been reported, generally within a few days of initiation of MOVANTIK. Monitor and discontinue if severe symptoms occur. Consider restarting MOVANTIK at 12.5 mg once daily
- Cases of GI perforation have been reported with the use of peripherally acting opioid antagonists, including MOVANTIK. Postmarketing cases of GI perforation, including fatal cases, were reported when MOVANTIK was used in patients at risk of GI perforation (eg, infiltrative gastrointestinal tract malignancy, recent gastrointestinal tract surgery, diverticular disease including diverticulitis, ischemic colitis, or concomitantly treated with bevacizumab). Monitor for severe, persistent, or worsening abdominal pain; discontinue if this symptom develops
- Avoid concomitant use of moderate CYP3A4 inhibitors (eg, diltiazem, erythromycin, verapamil) because they may increase the risk of adverse reactions. Use of strong CYP3A4 inducers (eg, rifampin, carbamazepine, St. John’s Wort) is not recommended because they may decrease the efficacy of MOVANTIK. Avoid concomitant use of MOVANTIK with another opioid antagonist due to the increased risk of opioid withdrawal
- The use of MOVANTIK during pregnancy may precipitate opioid withdrawal in the pregnant woman and the fetus. Because of the potential for adverse reactions, including opioid withdrawal in breastfed infants, advise women that breastfeeding is not recommended during treatment with MOVANTIK
- The most common adverse reactions with MOVANTIK as compared to placebo in clinical trials were: abdominal pain (21% vs 7%), diarrhea (9% vs 5%), nausea (8% vs 5%), flatulence (6% vs 3%), vomiting (5% vs 4%), headache (4% vs 3%), and hyperhidrosis (3% vs <1%)
MOVANTIK® (naloxegol) is indicated for the treatment of opioid-induced constipation (OIC) in adult patients with chronic non-cancer pain, including patients with chronic pain related to prior cancer or its treatment who do not require frequent (eg, weekly) opioid dosage escalation.
